Description
Technical field
The invention belongs to the special type knife technical field, more particularly relate to of the improvement of processing endoporus annular groove with grooving cutter.
Background technology
The endoporus annular groove is usually used in the occasions such as installation of circlip for hole, is one of machining element of machine components.The traditional diamond-making technique of endoporus annular groove is in Vehicle Processing on the lathe or the processing of the boring on the boring machine.Add repeatedly tool setting in man-hour, repeatedly turning, repeatedly measure.Therefore, this processing method efficient is very low, time-consuming, and production cost is also high, and each endoporus annular groove must repeat above-mentioned process one by one.In addition, this processing method can not be processed on better simply lathes such as drilling machine.
The patent No. be ZL94110803.1 and ZL99227980.1 patent disclosure two kinds of pore groovings or boring tool.Efficient height when it is used to produce in batches also can be processed on better simply lathes such as drilling machine.But the working depth of its endoporus annular groove (depth of cut) is regulated, the Working position of endoporus annular groove is regulated, and can only rely on the adjusting cutter.Though the endoporus annular groove grooving cutter that has can be regulated Working position among a small circle, it is to rely on the advance and retreat of the screw of cutter end to regulate, and can only be used for blind hole and can not be used for pore.In addition, its adjustment can only be qualitative can not be quantitative, more do not have scale to be indicated, thereby adjust very inconvenient, time-consuming.
Summary of the invention
Purpose of the present invention, just be to overcome above-mentioned shortcoming and defect, a kind of not only repeatedly tool setting, repeatedly turning are provided, repeatedly measure, working (machining) efficiency height, quality are good, can on better simply machining tools such as drilling machine, process, and working depth (depth of cut) and Working position all can quantitatively adjust by scale, adjusts the grooving cutter of endoporus annular groove processing very easily.
In order to achieve the above object, the present invention includes the eccentric bushing of anterior band eccentric inner hole rear portion band taper shank, be sleeved in the eccentric inner hole of eccentric bushing and have the spiral fluted knife bar, the screw of processing on the eccentric inner hole sidewall, be installed in the steel ball in the helicla flute of this screw and knife bar, be installed in the holding screw of in the screw steel ball being located, be sleeved on the big stage clip that is positioned at the knife bar back in the eccentric inner hole, be installed in the little bearing and the big bearing of knife bar front portion, be sleeved on eccentric bushing outside and the externally threaded sleeve of two ends band and be installed in two positioning sleeves up and down and locknut thereof on the external screw thread of sleeve two ends respectively.The front portion of knife bar is installed with handle of a knife, in the top wire hole of knife bar front end or handle of a knife jackscrew is installed handle of a knife is located, and lathe tool is being fixed in the handle of a knife front portion.Unscrew jackscrew, just can adjust the position of handle of a knife or change handle of a knife.After location-appropriate or the replacing, tighten jackscrew again and get final product, very convenient.
Screw on the eccentric inner hole sidewall should be positioned at the thickest place of eccentric inner hole and eccentric bushing outside.The effect of steel ball is a guiding.It can only roll and can not move, and half is positioned at helicla flute, and half is positioned at screw, is positioned between helicla flute, screw and the holding screw.When the holding screw inner face is recessed end, be more suitable in the location.
When the spiral fluted number of turns was half-turn, the last amount of feeding of lathe tool that is the working depth of endoporus annular groove just equaled the twice of the eccentric throw of eccentric bushing.The spiral fluted number of turns is convenient to the adjustment of processing capacity.
The outside, two ends of sleeve is processed with facet, has axial rule on the facet.
Adjustment is installed in the following positioning sleeve of sleeve lower end and the position of locknut thereof, can adjust the grooving position, and adjustment is installed in the last positioning sleeve of sleeve upper end and the position of locknut thereof, can adjust the number of turns of knife bar rotation, thereby cover has been put in order the depth of cut.Taper shank one end in this specification during with normal operation position is last.
The rear end of knife bar has centre bore, between the eccentric inner hole of centre bore and eccentric bushing small pressure spring is installed.This structure makes the tension force that resets bigger.
Be screwed into the position of sleeve upper end, the working depth that just can regulate the endoporus annular groove by positioning sleeve in the scale adjustment.In the time of will going up positioning sleeve and up twist, under the tension force effect of large and small stage clip, knife bar is subjected to downward pressure, is forced to along its helicla flute rotation downwards, until suffered tension force and reaction force balance.Original position when this moment, steel ball and spiral fluted relative position were feed.The depth of cut (that is working depth of endoporus annular groove) is finally determined by the remainder stroke of steel ball in helicla flute.Therefore, in the time of will going up positioning sleeve and up twist, the spacing increase of knife bar and eccentric bushing, the remainder stroke of steel ball in helicla flute reduces, and the depth of cut reduces.Otherwise in the time of will going up positioning sleeve and down twist, the spacing of knife bar and eccentric bushing reduces, and the remainder stroke of steel ball in helicla flute increases, depth of cut increase.The position that last positioning sleeve is screwed into sleeve can quantitatively be indicated by rule, has in fact also just indicated the depth of cut.After adjusting end, locknut should be twisted to lean against on the positioning sleeve and lock, to avoid the positioning sleeve positioning.
Be screwed into the position of sleeve lower end by positioning sleeve under the scale adjustment, just can regulate the Working position (being the size of endoporus annular groove) of endoporus annular groove apart from the endoporus upper edge.This is readily appreciated that.Handle of a knife to be goed deep in the hole together with lathe tool because add man-hour, and finally need to descend the lower edge of positioning sleeve to be resisted against on the upper edge of endoporus.Therefore, when down backing out positioning sleeve, move on the Working position of endoporus annular groove, that is its size from the endoporus upper edge reduces.Otherwise when up backing out positioning sleeve, the Working position of endoporus annular groove moves down, that is its size from the endoporus upper edge increases.That is to say that following positioning sleeve is with respect to the displacement displacement of endoporus annular groove Working position actually of rule.After adjusting end, locknut should be twisted to lean against down on the positioning sleeve and lock, to avoid down the positioning sleeve positioning.
Little bearing and big bearing are thrust ball bearing.Little bearing is the location benchmark with the knife bar, and big bearing serves as the location benchmark with the sleeve endoporus.Add man-hour, knife bar and eccentric bushing mainly bear axial force, and thrust ball bearing can be competent at the extruding of axial force, and be particularly suitable.The still of low thrust ball bearing is the location benchmark with the knife bar, and the still of high thrust ball bearing serves as the location benchmark with the sleeve endoporus.This structure can guarantee that the relative motion between knife bar and the sleeve is rolling friction.
Basic functional principle of the present invention and using method are with the applicant's ZL03253353.5 patent.
Not only repeatedly tool setting of the present invention, repeatedly turning, repeatedly measurement, working (machining) efficiency height, quality are good, can on better simply machining tools such as drilling machine, process, and working depth (depth of cut) and Working position all can quantitatively adjust by scale, adjusts the grooving cutter of endoporus annular groove processing very easily.It can be widely used in the batch or single-piece production of endoporus annular groove.
